Things to Consider When Buying A Flat Iron For Curly Hair

Things to Consider When Buying A Flat Iron For Curly Hair

When you have curly hair, you need a straightener that can do more than smooth your locks. You need a flat iron that can change your hair’s texture and give you lasting results. 

These are a few things to keep in mind when picking out an iron:

Temperature Settings

You’ll need temperatures of at least 350 degrees to straighten curly hair. Your hair is more likely to respond to the iron when the temperatures are high. 

Frizz

Straightening your hair can dry it out, leaving you with lots of frizz. You can minimize this by choosing an iron with ceramic or titanium plates. 

Price

Your budget is likely to have a major factor in your final decision. Flat irons can cost anywhere from $20 to $250, which means there are options for every price point. 

Plate Size

Long and wide plates are best for straightening curls. Look for a flat iron with a plate size of 1″ or higher.

Do Flat Irons Damage Curly Hair?

Flat irons can be very damaging to your curls, especially if you choose the wrong straightener or use your iron incorrectly. It’s best to choose an iron with ceramic or titanium plates that can protect your hair from excess heat. 

Damage is much more likely to occur if you try straightening your hair while it’s wet or even damp. 

Flat irons heat to very high temperatures, and when you apply these temperatures to wet hair, you can seriously damage your hair cuticles. Comb out any tangles, let your hair air dry, and then use a straightener. 

You can also reduce damage by applying a heat protectant product to your hair while it’s still damp. Your hair will absorb the product, allowing it to form a protective barrier over every strand of hair. 

Lastly, you should make sure you don’t straighten your hair every day. Curly hair is usually dry and porous, which means it doesn’t always have to be washed every day. 

If you think your hair is looking a little oil, use a dry shampoo to get rid of oil without washing your hair.
